Grafana Labs is seeking a Senior FullStack Engineer to build and scale Real User Monitoring (RUM) capabilities within Grafana Cloud, a fully managed observability platform trusted by over 10,000 organizations including Anthropic, Bloomberg, NVIDIA, Microsoft, and Salesforce.
In this role, you will own end-to-end fullstack features for RUM, spanning frontend user experiences through backend services, APIs, and storage systems. You'll design and implement systems that ingest, store, and query high-cardinality, high-volume telemetry data (sessions, events, traces, logs) using columnar and analytical databases. Your work will include developing performant query layers and APIs that power real-time exploration of user sessions and events, contributing to frontend applications that visualize RUM data to help users debug performance issues and understand user behavior.
Key responsibilities include:
- Building fullstack RUM features from frontend through backend services and storage
- Designing systems for ingesting, storing, and querying high-volume telemetry data
- Developing performant query layers and APIs for real-time data exploration
- Contributing to frontend applications for RUM data visualization
- Optimizing data modeling, indexing, and query performance for low-latency, cost-efficient analytics
- Collaborating with SDK engineers (browser and mobile) on data ingestion and schema evolution
- Owning projects end-to-end from design through deployment and iteration
- Breaking down complex problems into incremental deliverables
- Ensuring quality through testing, observability, documentation, and smooth upgrade paths
- Cross-functional collaboration with backend, frontend, product, and solutions engineering teams
- Supporting teammates and shaping the RUM roadmap
Grafana Labs is a 100% remote company with team members across 40+ countries, backed by leading investors including Lightspeed Venture Partners, Sequoia Capital, and others.

REQUIREMENTS:
- 5+ years of fullstack engineering experience with strong frontend fundamentals
- Frontend experience with TypeScript and React
- Backend experience, with Go preferred
- Experience building or operating distributed systems in production (e.g., Kafka, WarpStream, Apache Pinot, ClickHouse, Cassandra, Postgres)
- Familiarity with cloud-native systems (Docker, Kubernetes, AWS, GCP, Azure)
- Experience working with high-throughput, high-cardinality data (logs, metrics, traces, events)
- Strong understanding of data modeling, query optimization, and performance tradeoffs
- Experience designing and building APIs and distributed services
- Experience building data-heavy UIs (dashboards, query tools, debugging interfaces)
- Familiarity with observability concepts (traces, logs, metrics) and/or OpenTelemetry
- Strong communication skills and ability to work in remote, distributed teams
- Pragmatic, self-driven approach and comfort navigating ambiguity
- Customer-focused mindset with passion for developer experience
BONUS/NICE-TO-HAVE:
- Experience with browser or mobile instrumentation (RUM SDKs, telemetry collection)
- Mobile development experience (iOS or Android) or familiarity with mobile performance and telemetry
- Contributions to OpenTelemetry or other observability open-source projects
- Experience building developer-facing platforms or observability products
- Familiarity with session replay, sampling strategies, or user behavior analytics systems
